Dewey,

That sounds perfectly feasible. Hardened plugs that your file won't cut down past. Fixed to the hinge pin reference point and providing the required radius.

A marvel in simplicity.

Saves on all kind of jigs I've seen.

When we get too dependant on machinery we forget what magic can be done with files, buttons, squares, templates etc. It's the way it had to be done back before milling machines, lathes, shapers became more common..........let alone the "white man's magic" of cnc.

Thank you for explaining this.

Keep up the great work.
